  • At present the PCH has 4 operations and these are reasonably widely used
    in the drivers. But sometimes we want to add rarely used operations, and
    each of these currently adds to the size of the PCH operations table.

    Add an ioctl() method which can be easily expanded without any more impact
    on the operations table.

  • This uclass currently has no tests. Add a sandbox driver and some simple
    tests to provide basic coverage.

  • At present this uclass is selected only on x86. In order to add a test for
    it, it must also support sandbox. Create a new CONFIG_PCH option and
    enable it on x86 and sandbox.

  • When U-Boot started using SPDX tags we were among the early adopters and
    there weren't a lot of other examples to borrow from. So we picked the
    area of the file that usually had a full license text and replaced it
    with an appropriate SPDX-License-Identifier: entry. Since then, the
    Linux Kernel has adopted SPDX tags and they place it as the very first
    line in a file (except where shebangs are used, then it's second line)
    and with slightly different comment styles than us.

    In part due to community overlap, in part due to better tag visibility
    and in part for other minor reasons, switch over to that style.

    This commit changes all instances where we have a single declared
    license in the tag as both the before and after are identical in tag
    contents. There's also a few places where I found we did not have a tag
    and have introduced one.

  • On some newer chipset (eg: BayTrail), there is an IO base address
    register on the PCH device which configures the base address of a
    memory-mapped I/O controller.

  • x86 GPIO registers are accessed via I/O port whose base address is
    configured in a PCI configuration register on the PCH device. Add
    an op get_gpio_base to get the GPIO base address from PCH.

  • pch_get_version op was only used by the ich spi controller driver,
    and does not really provide a good identification of pch controller
    so far, since we see plenty of Intel PCH chipsets and one differs
    from another a lot, which is not simply either a PCHV_7 or PCHV_9.
    Now that ich spi controller driver was updated to not get such info
    from pch, the pch_get_version op is useless now.

  • At some point we may need to distinguish between different types of PCHs,
    but for existing supported platforms we only need to worry about version 7
    and version 9 bridges. Add a driver for the PCH9.

  • A Platform Controller Hub is an Intel concept - it is like the peripherals
    on an SoC and is often in a separate chip from the CPU. The chip is typically
    found on the first PCI bus and integrates multiple devices.

    We have a very simple uclass to support PCHs. Add a few operations, such as
    setting up the devices on the PCH and finding the SPI controller base
    address. Also move it into drivers/pch/ since we will be adding a few PCH
    drivers.
